What is your opinion of "Ultra-Turbo" SNGs?

[CmnDwnWrkn]

I typically play Turbo SNGs, where blinds escalate every 5 minutes, but UltimateBet also offers "Ultra-Turbo" SNGs, where blinds escalate every 2 minutes (!). Would anyone recommend playing these ultra-fast SNGs, or is it best to stay away? Obviously these go a lot quicker, and stack-to-blind ratios shrink very rapidly. What would be some of the advantages/disadvantages to playing in such tournaments? Ultimately, do you think the disadvantages outweigh the advantages, or vice versa, or is there not much of a difference from an hourly rate perspective either way?
